Terminal Emulator II

For telecommunications you can use your TI-99/4A with an RS-232 Interface and a telephone modem, plus the Terminal Emulator II command module.

If you have the Speech Synthesizer Module, you can even use it with this cartridge. There are two main ways to use speech, "text-to-speech" and allophone speech. The allophone speech can be more exact because you can specify certain sounds.
